IMPROVEMENT IN SUBMERGED PUMPS.

Specification forming part of Leiters Patent No. 46.764. datcd March 7,1865.

To all whom, it may concern:

Be it known that I, J. B. WILLIAMSON, of Branchville, in the county of'Sussex and State of New Jersey, have invented a new and Improved Pump;and I do hereby' declare that the following is a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specitication, in which- Figure l is a verticalsection of my invention, taken in the line Fig. 2; Fig. 2, a side viewof a portion ofthe same.

Similar letters ot' Iei'erence indicate corresponding parts.

This invention relates to a new and improved doubleacting pump; and itconsists in a novel arrangement of parts, hereinafter shown anddescribed, whereby a very simple and economical pump is obtained, andone which may be kept in repair or proper working order by any one ofordinary ability.

A represents a vertical post or standard fitted in the well from whichthe water is to be drawn or elevated, the lower end ofthe post restingupon the bottom of the well. This post or standard A is tubular and hastwo pump-cylinders, B B, attached to it at two Opposite sides and nearits lower end, the upper parts of said cylinders communicating by meansof passages a awith the interior of the post or standard A, the lowerend ot' each passage a being provided with a valve, b, opening upward,and the upper end ofthe passage cin A communicating with a nozzle, C,through which the water is discharged.

D D represent two yokes which encompass the cylinders B B and areconnected by rods d d to a brake, E, the fulcrum e of which is in theupper part of the post or standard, the rods d d being attached to saidbrake at opposite sides of the fulcrum e, as shown clearly in Fig.

l. The yokes D D are each provided with a piston, F, attached to theirlower ends by rods af, which form joints to admit of a lateral play ofthe yokes under the movement ot' brake E. These pistons are tubluar, asshown in Fig. 1, and they work in the cylinders B, passing into theirlower ends, each piston being provided with a valve,f, at its upper end,opening upward, and the upper ends of the pistons having a packing, g,around them.

The cylindersB B, it will be understood, are submerged, and by operatingthe brake E the yokes D D, and consequently the pisons F F, will bemoved up and down, thepistons working simultaneously in oppositedirections. As one piston, F, descends, its cylinder B is lled withwater, the valve b above being kept closed by the pressure of water uponit caused by the upward movement of the other piston, which forces thewater in its cylinder up into the standard A and out through the nozzleC, and as the pistons F rise and fall alternately it will be seen that acontinuous stream of water will be forced i'rom the nozzle C.

The arrangement is extremely simple and efcient. There are no partsliable to get out of repair-,and when repairs are necessary they may bemade by any one at all familiar with mechanics7 tools.

I claim as new and desire to secure by Let-- ters Patent- The tubularpost or standard A, with thc two pump cylinders B B permanentlyattached, with valves b at their upper parts, in connection with thereciprocating yokes D D, provided with thetubular pistons F F, havingValves f at their upper ends, all arranged to operate in the mannersubstantially as and for the purpose herein set forth.

I J. H. VILLIAMSON.
